MINERALS EXPLORATION

Minerals exploration, including air rotary and core drilling, require high quality products that will maintain core recovery and cuttings retrieval as well as hole stability while drilling. Our full lines of products for both applications ensure these goals are met in each application.

CORE DRILLING

Core drilling requires that we provide as close to 100% core recovery as possible. Core drilling fluids not only maintain a competent core during the drilling process, they also stabilize the surrounding formation so the coring process can advance. As a result, we require drilling fluids that provide cuttings removal, hole stability and lubrication. Our line of polymers and lubricants address all geological environments while providing the best core recovery. It is critical that our clients provide the best core information to the Mine since that will encourage further exploration.

REVERSE-CIRCULATION (RC)

RC drilling operations use simpler fluid systems yet obtaining accurate cuttings information is still critical to the operation. Water flows are often encountered and injected fluids must be modified to address these flows. Polymer and polymer blends are often incorporated into the foam-based drilling fluid to provide resistance to water flows. Our concentrated, high-performance hammer oil also ensures maximum hammer life and performance.

Our FOAM-STAR is a highly concentrated specialty foamer for all air rotary applications. STAR-GEL XTRA is a specially ground and formulated bentonite product that will mix quickly, thus preventing “spin-out” on the inside of the drill rods. Our full line of STAR-DRILL polymer products complement our other specialty products so that NorthStar Fluid Solutions customers can move forward on projects with confidence that they are getting the most for their dollar with the best quality polymers for these applications.

The primary goal in exploratory drilling is to provide the most information possible to mine geologists so that the richest mineral resources can be evaluated and exploited. The two primary methods to retrieve this valuable information are by core drilling and reverse-circulation drilling.

FAQ Products
You recommend product formulations for certain soil conditions - which product should I use in mixed conditions?

Your mud formulation should always address the more prevalent soil condition.

For example, if the formation is mostly sand, then you should formulate to treat sand in addition to the other anticipated geology.

What is the typical order of addition?

Make up water should always be tested and treated first. If you suspect you are working with hard water, then it should be treated with soda ash.

You should next mix your bentonite and give it time to hydrate for about 7-10 minutes.

Natural polymers like PAC and Trol should be added, followed by synthetic or PHPA polymers like Star Drill.

Liquid additives like clay control and lubricants should be added last.

Are your products environmentally safe?

All of our products undergo rigorous environmental testing.

We ensure the products used or recommended for your project meet all Federal, State/Provincial and local environmental regulatory requirements.

What is the benefit of using a liquid polymer?

Liquid polymer, although 30% or 50% active polymer content, will mix a lot faster and more efficiently than dry polymer.

Liquid polymers are typically used where hopper or high shear mixing systems are not available

Will powder polymers mix in any mixing system?

Readily dispersible powder polymers will mix more efficiently than standard dry polymers. We recommended that regular grade polymers are added very slowly to the tanks or through a hopper system.

Otherwise, dry PAC and Trol polymers should be pre-wet in vegetable oil or vegetable-based lubricants

Can I apply NorthStar dill rod grease to wet rods?

Yes, NorthStar drill rod grease is formulated to stick to wet rods.
